Efficiency. Theoretically, how much money you'll save on your power bill.

A short circuit that the SCP doesnt pick up on can draw infinite load on a single connector. This is where OCP is useful. A fan obstruction, or even the fan dying with overheat the power supply. This is why OTP is necessary. The G2 wouldn't have been a better choice. It has the same issues, if not worse.

That still doesn't tell us what factors are examined before tiering. Noise? Primary topology? Efficiency? Cabling? Not only is this necessary for validity, it also lets people know what further research they should take before buying.

This list is still filled with flaws. Which makes me believe this list isn't based on fact, just assumptions and subjectivity. I'm still waiting on the required criteria for each tier. What factors you take into account, what you don't.

Hm. Must've been thinking of another region. Sorry. Revisiting, your options are pretty much the Corsair CX450 for 3500 or Corsair VS450 for <2500. If you don't intend to upgrade, and don't mind the lack of modern sleep states the VS would be okay.

I haven't looked at the Indian market for a while, but I believe there's some be quiet system power 9, FSP "Hexa 85+", or Andyson M5 there. Those are decent, super cheap units.

Protection. Safety. That's all. Typo. The G2's OCP and OPP are obviously set very high. It completely lacks over temperature protection.

Think of a breaker box in your house. With a multi-rail PSU, Basically the power delivered to your system is split up into different segments (rails). Each of these rails have their own Over Current Protection, where it will safely turn the PSU off if there's too much power going through a rail. Rarely, a multi-rail unit can cause compatibility issues. Otherwise multi-rail is preferred. A single rail PSU will only have one segment (rail). This rail still has the over current protection (they actually use "Over Power Protection"), but it's set a much higher point. If there's too much power going out the PSU (either caused by a short or overpowered components), it can melt, start fires, kill components, etc.

Same platform. The main difference is the "non S" having four 12V rails while the S has a single 12V rail.

The G2 also has very high trip points and completely lacks OCP.

G2 above G3? Explain. Pure Power 10 above Corsair CX? Explain. Still have no clue what criteria you're using to grade these... Noise? EMI filter? Build quality? Topology?....

It's a guess because this list is subjective. It's based off how one person feels about the power supplies. I can't read minds. Then why are you asking for "tiers"? The power supply isn't complete crap. It atleast comes with a complete EMI filter with surge and inrush protection, and APFC. Quality is questionable. Though it's components aren't undersized, given the low capacitor quality, small heatsinks, sleeve bearing fan, I don't expect this unit to last past a few years. It's using a low quality, 8-pin protection IC. So it's missing some cruical protections such as OCP. I also didn't see any OTP implemented anywhere. What does this mean? You can't rely on the PSU not taking parts with it when it dies. Electrical performance is what you'd expect from a cheap double forward + group regulated unit. Voltage regulation is mediocre at best. Ripple is poor on the 3.3V rail. Not only is this unhealthy to your components' lifespans, it implies even less time before you start seeing reboots and PSU problems. Especially when paired with a high end CPU + GPU. And of course, no support for modern CPU sleep states. It's not quiet either, revving past 1000RPM at just a little over 100w load. You'd also expect coil whine when using a modern, high end GPU, as the PSU is using a double-forward design. Not sure why your friend even considered buying this PSU for his 2080ti system... I advise a new, high quality PSU.

Your power supply isn't good. http://translate.google.com/translate?depth=1&amp;hl=es&amp;rurl=translate.google.com&amp;sl=ru&amp;tl=en&amp;u=http://www.easycom.com.ua/power/thermaltake_smart_se_sps-630m/%3Flang%3Dru If I had to guess, since no one really knows the criteria in this PSU list, it would sit at T4 or T5.

No. No one should choose by brand. As a manufacturer, they aren’t the best. They are Tier 3, meaning they outsource their PCB-A. This could lead to worse QC as opposed to a tier 1 manufacturer. The Focus Plus is pretty good, if you can look past it’s OCP issues.

That's not even comparable to the Sama Armor. Group regulated, lacks protections, much less efficient. That's before we even delve into reviews.

No. They aren’t. Read a review: http://www.f14lab.com/2018/03/review-corsair-vs450-450w-2018.html You’ve been saying that for weeks. And I don’t think OP wants to wait another just for one more subjective list.

I suppose you might also want the best PSU for the best mini PC. Assuming the case can hold an ATX. Corsair AX1600i for just $340.

CWT. Platform is probably CSH-VG. Same as themaltake modular Tough Power Grands

Your PSU has ports for 8 PCIe / CPU cables. So you could just buy another compatible CPU cable, as @OrionFOTL said.

Be Quiet Dark Powr Pro 11 EVGA G2 GS GQ P2 G1+ 650 NZXT E Seasonic Prime Bitfenix Formula Aerocool P7 Coolermaster V and more if you really believe you need a dual EPS connectors for you 9900k, OP. 550w is fine.

Yes but buying a PSU is situational. Each of those categories should be easy to explain. E.g. Temp rating: Look for 40 or higher unless you’re in cold climates with good airflow into the computer. APFC: Where are you using the PSU. Primary topology: if you don’t want coil whine with a RTX 2070 or higher look for LLC resonant. DCDC: For sleep states and beneficial for most systems using a >75w GPU. Indication of voltage regulation if no review available. Efficiency and noise: Pretty self explanatory. Use a calculator to see if it’s worth. Bearing: Sleeve only last a few years, rifle a couple more, FDB and ball bearing for long life. You’ve been saying that for the past year about this list Im not sure how useful the Protection IC is. Because some protections are implemented in other ways. Perhaps just a list of protections, and if any rails are excluded such the HY-510N. And option for multiple review links. Some reviews miss useful information. Some reviews don’t even take photos. Date or release might be useful too. I’d be glad to help out with the list in any way.

It has four 12V rails. Two are rated at 18A, the other two are 20A. Alltogether the PSU can deliver a maximum of 45.8A of 12V power. Its just Protection.

Amps on 12V are like wattage. Make sure it’s enough then forget about it. There are much more important aspects in a PSU. Most decent power supplies can supply 100% of their power on their 12v rail anyway. Your system is fine with a good 500w+ PSU / 41+ amps. No, it doesn’t simply add up like that. A good 550w PSU would have about 45A on the 12V rail. PSUs with multi-rail mean they have multiple Over-Current-Protections on the 12v line. Think of it as each connector having its own OCP as apposed to just using one OCP for everything. Essentially, if there’s a short or over current draw a multi rail PSU will pick up on it faster and more reliably The Straight Power 11 is a very high quality PSU. If you can afford, I’d go for that.

It may cause coil whine, isn’t compatible with modern CPU sleepstates, isn’t very efficient or quiet. It’s just rated for 30°C, and non modular. Its performance isn’t very good, especially with powerful, modern components. So I’d expect a shorter lifespan before things start going out of spec, causing reboots. Nor is the low voltage regulation very healthy for your components. But it isn’t junk. It still has a full EMI filter including surge and inrush Protection, overrated components, mid-level caps, decent hold-up time and most importantly a full set of protections. So unless something from the first paragraph bothers you, the PSU is fine to use temporarily. I also suggest the Corsair RM550x as the replacement, as opposed to the Focus Plus. The Focus units has issues with its OCP. Evidence? You cant jump to conclusions after noticing a couple example. Any PSU can potentially take out components. Dont forget the Corsair CX is one of the most popular units on the market.

How is the G2 a much better unit than the G3...?
